Went over 1K miles yesterday and my Roto-fab came today, installed it with no problems. It was packed great, good directions and video, awesome fit. I am a happy and blessed man. Thank you Roto-fab and RDP!

No dyno yet, still breaking it in....however it sure does seem to pull stronger. Sounds better and can hear the supercharger whine more!
Had one on my SS as well. simple/easy install, great instructions, seems to be well made. I am glad I got it!

Has there been any documented increases in performance or is this mainly for sound/"driver experience"?

We did some testing on a 100% stock ZL1 with nothing but the Roto-Fab intake installed and made a solid 31hp over stock. Mind you, this test was done with the hood up, but I have no doubt that complimented with the Big Gulp; you would see those gains at speed.
